I was going to pre-order like I did with FO:NV. Now I'm waiting because of the possibility that spell creation has been removed. I will certainly buy Skyrim, but if it is released on time... that means Steams Holiday sales is around the corner and for me it comes down to this:
No Spell Creation = Buy On Sale
I understand where you're coming from.
I'm getting to the point more and more that I can't fathom buying it on release day at all; buying later gets you a better product (Patches are out), at a cheaper price, and gives you the same amount of enjoyment out of the product.
I've managed to get myself about 2 years behind on game releases, which works perfectly for me. I can buy games on the cheap, and they're just exactly as new from my perspective.
